Thanks for the input guys,particularly ozpricey,that was the type of answer that makes the most sense to me.
Going to bite the bullet and upgrade to the redline after rigging the 2011 6.2 blade on the weekend. The battens around the boom area didn't sit that well on the powerex and seemed particularly back handed compared to the 08 blade on the powerex(using the rigging specs on the bag).
Kman 5000 had his same sail rigged on the redline and the battens sat much better on it and no ripples where they shouldn't be on the sail.
Still going to keep the powerex for those sketchy big days.
New enigma boom too, ouch I am poor now!
You can now book that holiday Ben
